Abstract: A rewrite component automatically generates rewrite rules that describe how uniform resource locators (URLs) can be rewritten to reduce or eliminate different URLs that redundantly refer to the same or substantially the same content. The rewrite rules can be applied to URLs received when crawling a network to increase the efficiency of the crawl and the corresponding document index generated from the crawl.

Abstract: Systems and methods for triggering actions are set forth. According to one embodiment, a method comprising determining at least one triggering condition associated with an article, correlating the triggering condition with information associated with a user, and providing the user with a notification relating to the triggering condition is described.

Abstract: Detecting so-called “navigation bars” (or “nav bars”) in a (Web) document by determining whether or not nodes of a parse tree of the (Web) document are “anchor-heavy”. Generally, a navigation bar can be thought of as text, such as a hyper-text link or anchor text for example, without any immediate content. Once a navigation bar is detected, objectionable navigation bars (i.e., navigation bars, the rendering of which would be objectionable to users without special re-authoring), can be distinguished from non-objectionable navigation bars (i.e., navigation bars which would not be objectionable to users with no special re-authoring).

Abstract: A method and system for recognizing the characters on surfaces where alphanumeric identification code (“ID” for short) may be present such as a license plate. The present system is particularly adapted for situations where visual distortions can occur, and utilizes a highly robust method for recognizing the characters of an ID. Multiple character recovery schemes are applied to account for a variety of conditions to ensure high accuracy in identifying the ID. Accuracy is greatly enhanced by taking a comprehensive approach where multiple criteria are taken into consideration before any conclusions are drawn. Special considerations are given to recognizing the ID as a whole and not just the individual characters.
